Application February 11, 1950, Serial N o. 143,786
This invention relates to improvements in mops 'and comparable devices for cleaning floors and walls. More particularly it provides improvements in mops and the like wherein la sponge constitutes the cleaning element and a handle is removably secured to the sponge to facilitate movements of the sponge over the surface of a floor or wall which is being cleaned.
Mops of the general type to which the invention relates have been Iavailable heretofore but the manner of removably mounting the sponge on the supporting head of the mop has not been entirely satisfactory, and all of the prior mops of this general type, so far as I am aware, have been open to the objection that rigid parts of the sponge-supporting heads frequently come into scratching or otherwise marring contact with the surface being-cleaned or with an adjacentsurface along whichthe sponge is being moved.
It is among the objects of the present invention `to provide 'a sponge-type mop having irnproved means for effecting removable connection of a sponge to the supporting head of the mop, whereby the sponge'is'more effectively secured to its supporting head and more readily removable and replaceable, as compared with the prior comparable mops of which I am aware. I provide a fabric member which is cemented and/or stitched to the sponge and which has side flaps for folding inward over side flanges of a rigid backing-plate-element of the head,
each side iiap of the fabric member having ar rigid edge-bead thereon adapted to be clamped against the backing-plate element, inside the-side 5 Claims. (Cl. 15-244) flanges of the latter, byY a clamping plate to'.V
which the mop handle is rigidly secured. K
Another object is to provide a sponge-type mop having its sponge removably secured to a rigid backing-plate element of the'rrnopV head and having al1 edge portions of the backingplate element protectively covered, or adapted to become covered in use of the mop, whereby no rigid edges of the backing-plate element can come into scratching or other marring contact with a surface along which the sponge is being moved. According to the invention, a fabric-v member 4is secured'to the sponge and removably! secured to'the backing-plate element, with portions of the fabric member enclosing edges of the backing-plate elementV or extending to Vpositions for protectively covering exposed edges of erally to improve sponge-type mops and more particularly the means for removably securing a sponge to a mop handle.
In the accompanying drawings:
Fig. 1 is an elevational View of a sponge-type mop embodying features of the present invention, the major portion of the handle being broken away;

Fig. 10 is a cross-sectional view on line II-Ill of Fig. 8 but showing a brush yattachment in place on the mop of Figs. 7 and 8.
Referring to the drawings, and more particularly to Figs. 1-6, a rectangular sponge II) has a Yfabric sheet member I2 cemented or otherwise secured to its upper surface. Preferably,
y the sheet member I2 will beof canvas or duck,
said element when the lsponge yields, in use,
with a marginal portion at each side and veach end folded inward as best seen in Fig. 4s, where the in-folded end'margins are represented at I4, I6 and the in-folded side margins are indicated at I8. 20. The in-folded margins are stitched across the ends of member I2, as at 22, and are stitched along the sides of member I2, as at 24, the stitches at 22 at the ends being relatively close to the fold lines, while the stitches atl 24 along the sides are spaced inward from the fold lines to provide a pocket along each side edge of member I2 within which a relatively rigid rod 26 is enclosed. Actually, the side stitching at 24 may be ldone after a rod' 26 has been; positioned within a folded side margin I8, 20 although, if desired, the side folds `maybe stitched at 24 to provide pockets into which the rods 25 may be inserted endwise, in which` case, the end stitching at 22 will be done subsequently at at least one end of the member l2, so that the rods 26 may be inserted through an open end of each side pocket, after which the open ends of the pockets will be closed by the end stitching at 22. If the stitching at 24 is done while the rods are in place within the marginal folds I8, 28, the end stitching 22 along both ends may be done before stitching along the lines 24.
The sheet member I2 also is folded upon itself' along two parallel lines a little inward of the edges of the infolded side margins i8, 2B and are stitched as at 28, these latter stitched folds determining the width of sheet member I2 which will be in contact with the sponge I0, as best seen in Figs. l, 3 and 6.
A rigid plate 3e has length a little less than the .fabric sheet member i2, and has. upstanding side flanges 322 over which side portions of the fabric member l2 may be turned to bring the enclosed rods 2i?I on the inside of the plate flanges 32. The flanged plate 38 has width slightly less than the width. of fabric. member lf2. between the fold stitches. at 2S, so that its anges ft2 may enter between the two thicknesses of fabric along the irl-folded side margins t8, 28, with the end stitches 22 confining Vthe flanges against endwise movement relative to fabric member i2. and maintaining end portions. of the fabric member i2 in covering relation te the end edges of the flanges.
After the plate flanges 32 have been inserted between the two thicknesses of fabric along the in-foldedside margins t8, 28, rthe enclosed rods 26 are pressed inward and downwardly so as to extend along the inner sides of iianges 32.
A relatively small clamping plate 34 next is secured in place on the rigid. plate element 38, it having lips 36 along its opposite side edges for engaging the enclosed rods 26 for forcing them downward during the secur'ement of the clamping plate 3ft to the plate element 38. This see curement of clamping plate 34 may be accomplished in any suitable manner, as by the wing nuts 38 on screws 4% which latter may be xed to plate element 350,. as in Fig. 6, and extend loosely through holes in clamping plateA 34. Conveniently, the clamping plate 34 may have a socket member 42 thereon for reception of a handle 44 to which the socket. member may be secured in any suitable manner, as by being. of split conl struction with projecting spaced ears: 4B by which the socket walls may be closed upon the handle 32 ofl plate member 30` 'are effectively enclosedand protected against contact. with a. surface along which. the sponge II] is being wiped. The sponge itself projects a little beyond the fabricl member I2 at both sides and. both ends of the: mop- When an end. of the sponge is: pressed to cover and protect the end edge of plate element 30, where it extends between the plate flanges, as seen at 52 in Fig. 2. The ends of the flanges are covered by the stitched infolded end portions of the two thicknesses of fabric between which the main extents of the flanges are enclosed. Hence, no metal or other scratching or marring element of the mop can come in contact with any surface along whichV the mop is being moved. Actually, when the sponge is secured to its backing plate, four double thicknesses of the fabric I4 are relatively closely associated in projecting relation to each end of each iiange of the backing plate, as best seen in the end views of Figs. 1 and 7 wherein each portion of the fabric between adjacent lines is a folded double-thick edge due to the infolded end margin I6 and the infolded side margins i8, 20, as clearly shown in Fig. 4. In Fig. 5, the fabric between adjacent parallel lines is folded fabric of two thicknesses of the fabric sheet. These fourfold projecting portions of the fabric constitute cushioning bumpers at the opposite ends of the mop for resiliently and harmlessly and noiselessly engaging mop-boards', walls or furniture, as compared with the prior harmful and noisy engagements of solid parts of the prior mops under similar conditions.
It should be noted also that each fold of the fabric secured by the stitches 28 constitutes a yieldable bumper rib projecting outwardly from and extending along each of the covered flanges of the backing plate. If the sponge yields in A* use, or shrinks, to the outer edge of one of these side bumper folds, the folded fabric bead yieldthat sponges Ic will be quicklyv interchangeable.
against a surface, the sponge will Vyield and; the
extra Iengthof the fabric member i2will.r 'yield Figs. 7, 8 and 10 illustrate a modied form of mop, or comparable cleaning device, wherein the fabric member I2 may be substantially the same as in the Figs. l-ir form, but the sponge I0 is stitched at 54 to the fabric member I-2 along both sides of the member I2. This stitching preferably will be in addition to a cement securement of the sponge to member I2 although the stitching alone in some cases may be adequate.
The clamping plate 34 of the Figs. 7, 8 and l0 form requires'but a single wing nut 38 and screw 40 for securing it in place on a plate element 30" which may be in all respects the. same as plate element 30 excepting that the edges of the side flanges 32 of plate element 30 are not turned over upon themselves, it being assumed that flanges 32 will have adequate inherent rigidity without any stiifening due to a turnedover edge. The socket member 42 is integral with clamping plate -34, it being represented as formed from a sheetl of metal with opposed edges turned inward to provide a key 58 for slidably engaging in a longitudinal slot 60 in a handle 44. A set screw 62, or the like, may secure the handle against pulling out of the socket member.
While the sponge I0 or I8' ordinarily is adequate for effectively cleaning floors and walls, it sometimes is desirable to apply a greater scrubbing force to particular regions than can be applied with a sponge. For this purpose, a bristlebrush attachment is shown in Fig. 10, clamped in place by the same wing nut 38 which secures the clamping plate 34. The brush 64 projects outward a little beyond the plane of one side of the sponge l0', generally opposite the socket member 42', and may have any desired length less than the'length of the plate elements ,'30. Its mounting bracket will have a foot part 66 for resting on the clamping plate 34', and an upstanding part 68 fitting snugly against a lip 36 of the clamping plate 34', whereby the single wing nut securement can clamp it securely in place. Obviously, a similar bristle-brush attachment may be mounted on the mop of the Figs. 1-6 form, in which case the mounting bracket would have spaced foot portions for clamping engagement by the two wing nuts 38.
If desired, a conventional squeegee device for wiping windows may be mounted on the mop in place of the brush 54, by means of a bracket with foot parts 66 similar to the bracket as illustrated for the brush.
